8 × Gigabit Ethernet ports (10/100/1000 Mbps) total.

Ports 1-4 support Power-over-Ethernet (PoE) (IEEE 802.3af and/or 802.3at) — meaning you can power devices such as access-points, IP-cameras, VoIP phones via the Ethernet cable. 

Total PoE power budget is around 60W (or higher depending on the regional spec) so you need to check how many watts each device draws. 

Non-managed (“plug and play”) operation: no configuration needed.

Fan-less design (quiet) suitable for deployment in offices, small server room.

Features like Auto MDI/MDIX on all ports (so no up-link cable issue), energy-saving features (link status, cable-length discovery).

Metal chassis, desktop or wall-mount possible in some locales
